Cloaking device

A cloaking device is an advanced stealth technology that causes an object, such as a spaceship or individual, to be partially or wholly invisible to parts of the electromagnetic (EM) spectrum. Fictional cloaking devices have been used as plot devices in various media for many years, but developments in scientific research show that real-world cloaking devices can obscure objects from at least one wavelength of EM emissions.

In 2008, physicist Michio Kaku predicted that a viable invisibility shield like the ones in Star Trek could emerge from laboratories in a few decades, quoting David Smith of Duke University used a metamaterial to bend light around an object and German scientists have fabricated a metamaterial that could redirect red light round an object.
